FretBoard Screen Overview 1

Rootnote and Chord/Scale Type Selection
This section at the top displays the current rootnote and the selected chord or scale. The user can interact with this area to select from different musical scales or chords to visualize on the fretboard. The rootnote is selected in the Magic Notebar (see below)

Chord/Scale Selection
Tapping the header part of the interface opens a menu where users can browse and select from a comprehensive list of chords or scales. Once selected, the fretboard updates to display the chosen chord or scale.

The star icon allows users to mark scales or chords as favorites for quick access later. This feature is beneficial for users to keep track of their most-used or preferred scales and chords.

Magic Notebar
By tapping a note name in the magic notebab, users can quickly change the rootnote. It’s designed for ease of use, enabling rapid changes to the displayed scale or chord on the fretboard.

Flat/Sharp Rootnote Switch
This toggle lets the user switch the rootnote labels between flat (♭) and sharp (#) notations. This is particularly useful for learning and comparison purposes, especially in genres or musical contexts where one notation is preferred over the other.

Settings Access
The settings gear icon provides quick access to the app’s settings, where users can customize their learning experience further, adjusting visual aspects, sounds, and other functionalities to suit their preferences. (see below)

Playback Controls
This section includes controls for starting or stopping playback, setting the direction of playback (ascending, descending or both), choosing octaves, and adjusting the playback speed in beats per minute. It offers an interactive way to hear how the selected scales or chords sound.

Note Labels Switch
Users can switch the note labels to various modes such as Enharmonic, Easy, Function, or None. This helps in understanding the theory behind the fretboard, showing the musical function of each note within the scale or chord, and also allows for a cleaner display without labels if preferred.

The color-coding system in FretBoard Evolution is designed to help users visually distinguish between different types of notes within chords and scales:

Rootnotes: Red
The rootnotes are the fundamental notes upon which chords and scales are built and are always displayed in red. This makes it easy to identify the starting point of any chord/scale.

Fifths: Blue
The fifth interval is a critical component of many chords/scales and is always shown in blue. This helps users quickly locate the fifth in relation to the rootnote.

Remaining Notes: Green
Notes that are part of the chord or scale, but are neither the root nor the fifth are displayed in green. For chords these are the basic notes that complete the chord.

Extensions: Yellow
Any extensions to a chord, such as the 9th, 11th, etc., which add more color and dimension to the harmony, are always highlighted in yellow. In scales you will not see yellow notes.

This color-coding scheme is intuitive and allows users to visually break down complex chords into their constituent parts, making it easier to understand and memorize their structures.

Swap Nut: This setting changes the orientation of the fretboard display to suit the user’s preference, either mimicking a left-handed or right-handed guitar.
